Selected slices of the PXCT tomograms for PC–FA blend paste after five months of hydration at room temperature. (a) Horizontal slice of the electron-density dataset and (b) same slice of the absorption dataset. Some regions are identified as different component phases, based on the electron-density values, using the labelling system in Table 1[link]. Air porosity that is likely to be caused by portlandite dissolution is highlighted in pale brown. Tiny empty spaces, that are likely to be caused by chemical shrinkage, are highlighted in blue.
